From episode 12 (i think) of CBB, Howard Kremer talking about rappers shooting each other, and how you never turn on the news and hear "The rock group KISS has been assassinated by a rival group of jews dressed as monsters".

Maybe it's not so quotable, but a great moment in CBB is in EP111 (about 58 minutes in) when Scott Aukerman and Brett Gelman are talking about guest David Guy Levy, referring to him as a stupid person. That made me laugh. The episode also features the great Gelrap "Hi! How Are You".

“New No-No. Uh, if you’re my dad, then uh, I should be able to make you my son. If you call me son, I should be able to adopt you and call you son. Raise you. Support you. Feed and Clothe you. New No-No: Dad’s the son now!”

Bill Cosby Bukowski- "Shut the fuck up Tempist Bledsoe. I will fucking Tempist Bleed you out." and who could forget? "Shut up Kisha Knight Pullium. I will Kisha Knight Pull all of your hair out and make a sandwhich out of that and feed the sandwhich to your butt." and of course, "shut the fuck up Theo. This is your first and only Malcom Jamal Warning." Cosby Bukowski might be my favorite.

I don't remember any exact quotes but I loved conversation on the HDTGM podcast where they were talking about the spaghetti robot from Judge Dredd, it was one of the funniest things I have ever heard on a podcast
